wot, no chat function?
'Three other people are also looking at this exhibit on 80's educational computing. Type "/talk blah blah blah" to (e.g.) tell them about the BBC micro 6502 co-processor you have stored in your parent's basement...' :-)
It's a beautiful day in old Blighty, hotter even than former party capital Ibiza in the Mediterranean. Are you going to go outside? Heck no, you're a sunshine-shirking nerd who works with and reads about computers for fun. Plus there are horrible diseases. Fortunately for you, The National Museum of Computing (TNMOC) has some …
Unless things have changed since I was there a couple of years ago, the Bletchley Park Trust has the rebuilt Bombe and the museum has the rebuilt Colossus. The two are on the same site, but they’re separate organisations and you have to buy a ticket for both. Also you could only get from one to the other by going back to the main gate.
They are both worth visiting but the Trust’s cafe was bigger and did hot meals. My advice is to do the Trust in the morning, have lunch there and do TNMOC in the afternoon. The TNMOC cafe is fine for drinks and they have (or had when I went) some very nice mugs and tee shirts.
I recently went to Bletchley Park for a 10.30am entrance and due to the social distancing currently in place, visiting the exhibits took much longer than usual and even without looking at every exhibit in detail and having an hour for lunch, barely made the last showing of the film in the small cinema in one of the huts, so I doubt you'd do both BP and TNMOC unless you plan on an earlier start and a shorter lunch.
